      Using a caliper gauge, measure the intake valve guide bush bore diameter of the cylinder head.

      Cylinder bore diameter
      10.285 to 10.306 mm (0.4049 to 0.4057 in.)
      Select a new guide bush (STD or O/S 0.05)
      Bush size Bush bore diameter
      STD 10.285 to 10.306 mm (0.4049 to 0.4057 in.)
